Twosmall belts support the spindle in one direction, one located on eachside of a large drive belt which supports the spindle in the otherdirection. The two small belts are independently supported by freeturning pulleys which, by their positioning, control belt tension. Thelarge drive belt is supported directly or indirectly by the drive wheel.

DESCRIPTION Referring to FIGS. 1 and 2, a straight spindle A or spindlewith whorl A-l is supported between two small belts B and drive belt C.Each small belt B is independently supported by a free turning pulley D.The pulley D is in turn supported by a mechanism to move it forwards orback in relation to center of drive wheel J which supports drive belt C.Such a mechanism is shown by pulley support E and tension screw G.Pulley support E is hinged by pin F attached to base H. Rotating tensionscrew G, which is threaded through pulley support E and bears againstend of base H, in either direction will move the pulley D laterally ineither direction, tightening or loosening all.

belts.

Spindle A can be removed or inserted by decreasing tension in belts.This is simply done by turning one or both of the tension screws G sothat the pulley D can move toward drive wheel J. The spindle A is keptin place by increasing tension in belts. This is done by turning one orboth of the tension screws G and then adjusting both tension screws Gindependently to align spindle A and avoid drift when it is rotating.

Rotating drive wheel J causes spindle A to rotate through the frictionof drive belt C on spindle. Free turning pulleys D assure minimumfriction and wear on belts and spindle as well as smooth rotation andhigh speeds.

I claim:

1. In a spinning wheel apparatus, a drive wheel, a spindle having anaxis of rotation parallel to and spaced from the axis of rotation ofsaid drive wheel, a drive belt engageable with the periphery of saiddrive wheel and with the periphery of a medial portion of said spindle,said drive wheel having a diameter substantially in excess of that ofsaid spindle for rotating the latter at a higher speed than that of thedrive wheel, a pair of axially aligned spaced pulleys with their axes ofrotation parallel to and spaced from the axes of rotation of saidspindle and on the opposite side of said spindle from said drive wheel,a pair of belts engageable with said pulleys and with said spindle onopposite sides of said drive belt, and means mounting said pulleys forfree rotation.

2. Apparatus as set forth in claim 1 in which said mounting meansincludes means for selectively varying the spacing between the axis ofsaid pulleys and the axis of said spindle for varying the tension onsaid belts.

3. Apparatus as set forth in claim 1 in which said drive belt and saidpair of belts comprise the sole support for said spindle.

4. Apparatus as set forth in claim 2 including a base member, a pulleysupport pivotally attached to and extending upwardly from said basemember, said pulleys being journalled on said support, and threadedmeans carried on said support and engageable with said base for rockingand support and thereby effecting said varying spacing between the axesof said pulleys and spindles.

5. Apparatus as set forth in claim 1 in which said pair of belts andsaid drive belt are parallel to each other. l t l
